[Eco Bounty] mimo exchange Hamburger Menu UI Clipping and Visual Feedback Failure

1. Description

When clicking the hamburger menu on the right side of the header in the mimo v3 mobile interface, the menu overlay displays significant formatting and layer issues:

• Background Transparency: The menu background is fully transparent or dark, causing the menu text (e.g., "Swap," "Pools," "Bridge") to blend into the main app background, making it difficult to read.

• UI Clipping: The menu appears to be "cut off" at the top, with the "Important" notice banner overlapping or sitting awkwardly behind the first menu items.

• Sticky Header Conflict: The wallet address and network icons remain visible and layered incorrectly over the menu options.

2. Steps to Reproduce

1. Open mimo v3 in the ioPay mobile browser.

2. Click the hamburger menu icon (two horizontal lines) located in the top right corner.

3. Observe that the menu opens but fails to provide a solid background or a clear "Close" (X) transition that is easily distinguishable from the rest of the UI.

3. Actual Result

The menu opens as a transparent overlay where the menu items are barely readable against the DApp's background elements. The layout appears "broken" because the header icons and the notification banner do not clear properly when the menu is active.

4. Expected Result

The menu should open as a solid, high-contrast overlay that completely covers or dims the background content to ensure readability. Navigation items should be clearly separated from header icons.

### Suggested Fixes

1. Overlay Opacity: Increase the opacity of the .menu-overlay background to 1.0 or add a high-blur backdrop filter to separate the menu from the Swap interface.

2. Z-Index Correction: Adjust the z-index of the navigation menu so it sits above the "Important" notice banner and the wallet/network icons.

3. Close Button Logic: Ensure the "X" button replaces the hamburger icon clearly and has enough padding to prevent accidental clicks on the icons behind it.
